That's what I thought BUT can you tell me what the DIAMETER & LENGTH
of the shank of the screw part of the sight is ?
I order one from Brownells that was a 6 x 48 thread pattern BUT the diameter of the shank on the one that they sent me was just a tiny bit larger than the original one that came on the gun and thus would not fit.
The Midway USA Master Catalog #34 has some Marbles replacement sights listed on page 718 of the catalog which shows the shank size as being .10 inches. They are product numbers 931-404 and 934-503. These are listed as Extra-Lum Fiber Optic Green sights.
Do you think that those would be the proper diameter shank to fit the Topper model 58 ? I called Midway and they provide no technical assistance of the products that they sell.
